P: Edit In External Editor does not work/function

I cannot use any external editor in lightroom 4, I receive an error dialog with the following message:

Unexpected error performing command:
bad argument #1to 'lower' (string expected, got nil)

This worked fine in LR 3, since the upgrade to 4 I have started receiving this error message

I have this problem myself. Am anxiously awaiting the fix. How long will it take?

Mac 10.7.3

For me too. Nothing working in Edit in (PS CS5, Nik, etc.). Version in Portuguese (editar em)

A variant to this problem for me is that I can "edit in" PSCS5 as before but the file opens without any LR corrections applied. IOW just as it was imported.

My workaround is to export the files I wish to edit and then re-import them into LR.

Mac 10.6.8

Thanks. It is reassuring to know that this was the appropriate avenue to report the problem and that the team is working on it. Much appreciated.

Hi guys,

The team is investigating this issue to provide some guidance soon. Thanks for your patience and reporting this issue.

What I do not understand is that it works in the Beta version. When i re-install the beta version all works fine.

Something went wrong on the way when preparing the final LR4 version I guess.

For sure the NIK plugins are supported in LR4. This is because NIK almost instantly updated their pug ins.

You can see this when installing an older version of a NIK plugin. in that case it will only see the LR3 version in the install window. After installing the latest plugin of NIK it sees LR3 + LR4 in the install window.

I also ordered the LR4 software. And indeed if they do not fix it then it is useless and I will return the box and ask for refund.

For sure it will not get that far. (I hope)

I'm running LR4 on a MAC pro with Lion 10.7.3

Lightroom 4 does not support the latest NIK plugins that worked on the LR4 beta. When Can I expect a fix for this ridiculous problem? I have cancelled my order for LR4 since it is UNUSABLE in its current state.

Edit in PSCS5 causes this error message:

Unexpected error performing command: bad argument #1 to 'lower' (string expected, got nil)

And searching through various threads and forums the best I can find is this thread (which is closed for comment) http://forums.adobe.com/message/42492... but reinstalling PS doesn't seem like a reasonable solution for a bug in LR4.
Any fixes coming?

NIK plugins are not working anymore. LR4 with MAC 10.7.3 and complete collection of NIK.

It was still OK in the BETA version but the final release does not work. The plugin's still show up in " edit photo in xxxx" but nothing happens.

I tried to re-install the plugin but during installation it only sees the LR3 program but not LR4.

Only the export to HDR plugin works

I use the complete collection of the NIK plugin. Bought 3 months ago.
I use MAC 10.7.3

hope this can be fixed soon
